Doing a quick side by side comparison of the 'selfie in the woods' shot with a shot of a person with a beard on 500px ( https://500px.com/photo/89633601/ge-by-nika-topuria ), the F100 shot has similar levels of detail in the facial hair, despite being taken from farther away and with what looks to be a wider angle lens by my eyes. You can pick out single strands of hair and bits of fuzz on the subject's clothing, etc., as well.
Bokeh is, of course, massively better on the F100. And I'll take basically any of the Fujia films over the color grading in the iPhone.
Meanwhile, basically every single concert photo on flickr for the f100 absolutely destroys the iPhone in quality ( https://www.flickr.com/search/?text=nikon%20f100%20concert )
Looking at landscape shots, it does appear you'll get more detail out of the iPhone camera ( https://500px.com/photo/10782613/silent-chorus-by-chris-froe... ), so I can't claim it's universally better, but I think the idea that phone cameras "comprehensively" outperform quality film SLRs from the 90s is false.
